We call it a cocoon.
A caterpillar is the larva stage of a butterfly or moth. A caterpillar hatches from the eggs of a butterfly or a moth. After a given amount of time, it then forms a cocoon, a casing of filament spun from its own silk glands. The caterpillar remains in this cocoon for protection while its body transforms into a butterfly or moth.

The caterpillar remains in this cocoon for protection while its body transforms into a butterfly or moth.
It hatches from the pupa by splitting open its pupal casing and emerging. The wings are folded and damp when inside the pupal casing. Once emerged, it stretches its wings and pumps blood into them while the wings are setting. It sits this way for a few hours before it flies away.
A cocoon.
A butterfly does not spin a cocoon, it's pupa is called a chrysalis. A moth, however, spins a protective silk case which is known as a cocoon. A caterpillar spins either a cocoon or a chrysalis depending on its breed. After being incased it will be its transfirmation into a butterfly. The time spent in the chrysalis is different for each species of Butterfly, but when the metormorphosis is complete the new butterfly will break its way out of the casing of the chrysalis and spread its new wings for the first time. The butterfly will genrally cling onto the side of the chrysalis for an hour or so, to allow their wings to dry out, and enable them to fly for the first time. The time that a lava spends in pupation may be brief, as with the Monarch butterfly who only stay in a chrysalis for 2 weeks. However, some species enter into a dormant state when they start pupation and stay in this stage until the appropriate season. They mostly stay dormant through the winter months or during the dry season in the tropics.
The same as it is before it's fired - a casing. Some refer to an empty casing as a "shell" or "shell casing".
The gill casing is called the operculum
rine mollusc's homne
It is the casing that the thermostat fits into. Normally called a housing.
Any rifle that the firing pin strikes the bullet casing right in the center of the casing, causing it to discharge is called a "Center Fire Rifle." In contrast a "Rim Fire Rifle" the firing pin strikes the edge or rim of the bullet casing causing it to discharge.
The engine casing allows you to easily fit in a new motor for each flight. If you didn't have this the used motor would have to be cut out before you could fit a new one.
